TO WIIOMl IT MAY GONGERN.

Be it known that I, I. FREMONT COLBY, of the' city of Washington, District of Columbia, have invented new and useful Improvements in Coffee-Mills; and I do hereby declare, the following to be a full and. exact description of the same, reference being had to the drawings that accompany and form a part of thesewspecications, in which-- v Y Y Figure lis a perspective view of the mill in position for the grinding. Figure 2, longitudinal vertical section, showing arrangement of interior parts. Figure 3, view of front f mill as it would stand at rest. Figure 4, end view, with arrangement for pouring out the ground coiiee.`

' Figure 5, view of mill in position for discharging-the ground coffee. In-this view a portion of the fron't'is broken away, representing how thel small/ chamber or hopper is supplied from the larger chamber or reservoir B..

Letter A., box., Containing chambers Afor the ungronnd coffee, as also receptacle for the ground coli'ee. Letter B, a supply-chamber or reservoir, to contain a pound or two, or more, di' the roasted berries.

Letter C, a smaller chamber, also for the nnground colee, and may be called the hopper, as the berriesare fed from this to the grinding parts.

Letter Il, grinding-device, and may be within the box A, as represented in iig. 2, or it may be on the outside of the box A., as appears in fig. 8.

Letter E, chamber, for receiving the ground coiiiee.

Letter F, swing-plate, beneath which is the opening for pouringfout the ground coffee.

Letter g, a lever, being across `just in the rear ofthe grinding parte, as may bc seen in iig. 2. To the lefthand end of this is attached a wire, extending frontwa'rds through the side of the box A, bearing the thumb-nut it. By this nut the mill is regulated to grind coarser or finer, as one may desire. Y

Fig. 2 exhibits the top of the reservoir or box A divided, and one part of 'it hinged. This aiiords oppor tnnity for filling the box. v v

The object of my 'invention is to provide a coffee-mill that may be convenient to use without requiringto be nailed up or permanently attached, one that can be easily heldf/on the side of the table, as in iig-1, or in the lap, or'on theknee i .A nd, further, toso combine areservoiri'or containing a considerable quantity ofthe roasted coiIee-'beries that they may be supplied to the hopper` of the mill as required without any exposure to the air,'in order that the aroma of the coii'ec may be much bettorfp'reserved than when the canister is opened every time a little is gronnd. i

Also to have the mill always closed, so as to be free from iiies, spiders, roaches, and the like.

The'grinding parts may well be made of chilled cast iron.

For common family size, I make the wooden box A from ten to twelve inches in length, iive to six inches rorn top to bottom when standing, as in iig. 1, and three to four inches wide.

A Chamber C holds only a small portion of the unground coii'ee, but as the box is turned up, as yin iig. 5, to.

pour outa quantity of ground ccji'ee, the hopper C will bc replenished from thelargeinchamber 'Ihis arrangement of the two chambers, one by the side ofthe other, givcslargerl base and `less hcig-ht'than to arrange one over the other, and thus thc'steadiness, or easy vholding of my mill, which is a very noticeable feature.

When setting the mill away on the shelf, it.rnay be in position, as in g. 1, Eg. 3, or g. 4, and thusv is suited to almost any space into'which it may be convenient to put it. i

The coifee being always kept perfectly dry and free from the air, is'always in good condition for grinding, and has all its delicious aroma preserved.

The box A, or any portions' thereof, may be madeof' metal instead of wood, if desired.

What I claim as of my invention, and desire `to secure hyLetters Patent, ivs- Providing the coffee-mill with a supply-reservoir, B, in combination with thesmaller chamber C, and chamber E, all arranged `for the purposes specified and set'iorth.

In testimonywhereof, I have signed my name tothis specification in the presence oi' two subscribing witnesses.

' I. FREMON'I COLBY.
